relay for rear fog lamp

I'm trying to wire up a rear foglight in my civic and I've run into a bit of a snag. I bought an OEM combination switch off a type-r from a guy in the UK in hopes it would work. The problem being is that the switch on the combination switch for the rear fog is a momentary switch. Now ive looked through some of the diagrams people have listed showing circuits for momentary to constant, but they always show an dual outputs, I only need a single. So pretty much what im looking for is an answer on how to wire up the momentary to a single point with a basic on off feature. I've tried looking for/at the wiring diagram for a UKDM civic, but I couldnt figure out how they had converted the momentary to a constant.

See also Latched on/off momentary w/ brake kill. I use one ordinary SPST relay as latching relay, but you need to break the power (or coil +12V or gnd) for it to un-latch.

Does this momentary switch give a pos or neg output?
